SAE ARP 1870A:2012 PDF Download

The SAE ARP 1870A:2012 standard establishes the minimum requirements for the electrical bonding and grounding of various equipment installations used in aeronautical and aerospace applications.

The purpose of this standard is to ensure that there is an adequate low resistance return path for electric, avionic, armament, communication, and electronic equipment. This is important for effectively reducing the coupling of electromagnetic fields into or out of the equipment and for providing electrical stability to control currents and voltages caused by static charges and discharges. It also helps in suppressing the hazardous effects that may arise from such charges and discharges.

By meeting the bonding and grounding requirements specified in this standard, aerospace systems can achieve a reliable and stable electrical performance, as well as ensure electromagnetic compatibility and safety. This includes withstanding operating conditions and corrosion, making it crucial for maintaining proper functionality and reducing potential risks in aerospace systems.
